An Overview Of Solvent Management And Emissions Of Amine-Based Co2 Capture Technology
Faculty of Engineering University of Malaya
Increasing global carbon dioxide (CO2) emissions are a rising concern for the global climate change. Amine-based post-combustion CO2 capture (PCC) technology is one of the mature options to contribute to the mitigation of these emissions. The technology is approaching toward its commercialization. However, there are two important problems, which should properly be addressed, solvent management and the amine-based PCC emissions. Major losses in amines are due to the oxidative and thermal degradation. Concentration of oxygen (O-2) is the driving force for the oxidation. Temperature, CO2 loading and amine concentration affect both thermal and oxidative degradation. This manuscript reviews solvent selection, …

CO2 capture from gaseous effluents is one of the great challenges faced by chemical and environmental engineering, as the increase of CO2 levels in the Earth atmosphere might be responsible for dramatic climate changes. From the existing capture technologies, the only proven and mature technology is chemical absorption using aqueous amine solutions. However, bearing in mind that this process is somewhat expensive, it is important to choose the most efficient and, at the same time, the least expensive solvents. For this purpose, a pilot test facility was assembled and includes an absorption column, as well as a stripping column, an …

In last decades, significant concerns have been raised regarding the global warming effect. To date, about one-third of the total anthropogenic CO2 emission results from power generation using fossil based fuel and CO2 is the main contributor to global warming. Therefore, technologies for efficient capture of CO2 are becoming of great value. In this respect, Chemical-Looping Combustion (CLC) has received significant attention as a promising technology facilitating concurrent CO2 capture and power generation. This non-conventional technique employs a solid carrier, known as oxygen carrier, to supply oxygen and facilitates combustion process in absence of N2 diluted air. Therefore, the combustion …
